A little quirk I noticed. If I put the machine in suspend while an ethernet cable is plugged in to a switch (or if plugging it in after suspending), the green light from the ethernet/eth0 is still active.
Any ideas?
The same thing also happens while the machine is powered off, if I leave the AC adapter/charger connected.
and only on coreboot?
I can't recall but I did have laptops that would light the LED even when off, I always assumed it was the ME
The only thing that is supposed to be on is the EC. The Ethernet NIC isn't supposed to have a firmware, right? Else it would have a flash chip connected to it, right? It still has a very small eeprom for its configuration bits, and I think some bits are documented in some intel datasheets.
I hope that: * The computer is properly powered off when on battery, and that the NIC and its led are also off during suspend to ram. * There is no firmware or such that I missed, because I guess that this NIC can do DMA.
